A.3 Basic Protective Measures against Discharge of Static
Electricity
Ensuring a Good Ground Connection
When handling electrostatic sensitive devices, ensure that your person, the
workplace and packaging are grounded. In this manner you avoid static charge.
Avoid Direct Contact
As a general principle, only touch electrostatic sensitive devices when this is
unavoidable (e.g. during maintenance work). To prevent discharge energy from
reaching and damaging sensitive components, hold the components in such a
way that you do not touch the pins or the printed conductors.
If you have to perform measurements on an assembly, discharge your body by
touching a grounded metallic object before carrying out the work. Use only
grounded measuring instruments.
